【解析】
试题分析：because因为，后面接从句；because of因为，后面接名词或者名词性短语；with 带有，表示伴随状况；to对于，表示动作对象。句意：汤姆看起来不高兴。怎么了？——因为她的话，他生气了。Her word为短语，故选B。
考点：介词辨析
点评：英语介词的一个特点是一词多义，并且介词间语义交叉现象很多，习惯用法也很多，有时很难从词义上区分开来。故学习中要注意不断总结，结合语境结合基本词义多记一些介词的习惯用法。

Mary picked up a pencil and a piece of paper，saying，“Now，you want to earn money for the autumn camping trip，right?” Tom，her brother，nodded．He wasn’t able to go last year because he hadn’t earned enough money during the summer．This year he came up with a plan．
He made a necklace for his mother that everyone admired．They were surprised to learn that Tom had made it for her．Why not make more necklaces and sell them?
“OK，” said Mary，“The first thing you need to do is to figure out（计算）how much you have now．’’
“I have $20.00 in the bank，and $7.25 in my room，” explained Tom．
“That gives you a total of $27.25，” said Mary，“That is called your capital．The next thing you need to know is how much it will cost you to make each necklace．”
“Well，the pet shop wilt give me all the feathers the birds lose．I'll have to buy the beads（小珠子）and string，” said Tom．
Mary wrote on the piece of paper：
| CAPITAL $27.25 EXPENSES Feathers no coat String for lo necklaces $2.50 Beads for lo necklaces + $15.00 Total $17.50 |
“How much do you think you can sell such a necklace for?” asked Mary．
“Hmm，” Tom looked thoughtful and said，“There's a shop in town that sells almost the same kind of necklace for $ 7.50．If I charge（要价）$ 6.00，people will think that's a bargain．”
“OK．If you sell each necklace for $ 6.00，you'll make a good profit（利润）on each then，” said Mary．
“Hurray!” Tom cried，“If I sell 2.0 necklaces，I'll have enough from the profit for the camping trip and $10.00 left over．”
